Description

[Detailed explanation of the idea] The present invention relates to the structure of a stapler.

As shown in FIG. 1, a conventional stapler has a needle box 1, a pedestal 2, and a staple presser 3 mounted on a shaft 4 so that they can rotate relative to each other, and is loaded into the needle box 1. In this structure, a pusher 6 for pressing the staples 5 is slidably disposed inside the needle box 1, and a pusher plate 7 for pushing the staples 5 is provided on the staple pressing body 3. 8
is a spring plate that is integrated with the push plate 7 and presses the needle box 1 elastically.

According to this stapler structure, by repeatedly pressing the staple pressing body 3, the staples 5, which are constantly pressed by the pusher 6, slide, and the staples are pushed out from the needle box 1 one by one, and the staples are pushed out from the needle box 1 one by one. It will be folded at stand 2 and documents etc. will be inserted. However, since the staple presser 3 is elastically in contact with the needle box 1 via the spring plate 8, even if the staples 5 are used up and there are no staples 5 in the needle box 1, the staples 5 will not be retained after pressing. The staple pressing body 3 is pushed up and returned from inside the needle box 1 by the spring plate 8. In a stapler having such a structure, it is necessary to expand the staple presser 3 from the needle box 1 each time to check how far the staple 5 is in the needle box 1, which is troublesome.
Since it is almost impossible to check unless you expand the stapler 5, you may carry a stapler without the staple 5 to use it in a place where there is no staple 5, or you may repeatedly press the staple presser 3 without knowing that the staple 5 is missing. Work loss often occurs due to pressing the staple 5, and loading the staple 5 requires five operations.

In view of such conventional examples, an object of the present invention is to provide a stapler in which it is possible to easily know from the outside when staples are missing from the staple box, and in which staples can be easily loaded. be.

Hereinafter, the structure of one implementation of the present invention will be explained using FIGS. 2 to 6. The same or equivalent portions and parts as in FIG. 1 will be designated by the same numbers and redundant explanation will be omitted.

In the figure, 10 is one side plate of the needle box 1, and the staple 5
A loading port 11 is provided that allows loading from the side. Reference numeral 12 designates the other side plate of the needle box 1, and is provided with a long sliding hole 14 in which an operating shaft 13 protruding from the pusher 6 can slide. Reference numeral 15 denotes one side plate of the staple pressing body 3, which is formed so as to cover the loading port 11. Reference numeral 16 designates the other side plate of the staple pressing body 3, in which a notch 17 is formed in which the operating shaft 13 is slidably guided. Further, notches 7-1 are provided on both sides of the push plate 7, and engagement claws 6-1 are formed on both sides of the front end of the pusher 6.
A spring 18 is suspended between a pin 19 provided in the needle box 1 and a cut-and-raised portion 20 of the pusher 6, and constantly presses the pusher 6 in the direction of the staple 5.

Therefore, when pushing the staple 5 loaded in the needle box 1 with the pusher 6, the notch 7-
1 includes engaging claws 6- provided on both sides of the front end of the pusher 6.
However, when the last staple 5 loaded in the needle box 1 is pushed out by the push plate 7 and bent on the pedestal 2, the sixth staple 5 is not inserted and engaged.
As shown in the figure, the engaging claws 6-1 provided on both sides of the front end of the pusher 6 in the notch 7-1 of the pusher plate 7 automatically engage.
In addition, it elastically fits and engages.

Since the present invention has the above-mentioned configuration, the fingertip is placed on the operation shaft 13 protruding from the pusher 6, and the operation fraud 13
By sliding the pusher 6 in the long sliding hole 14 provided in the other side plate 12 of the needle box 1, the pusher 6 is moved back in the direction of the axis 4 against the elasticity of the spring 18. In this state, a series of staples 5 is loaded into the needle box 1 through the loading port 11 provided on one side plate 10 of the needle box 1. Then, press the staple pressing body 3, and press the staple pressing body 3.
This is the same as the conventional method in that the staples 5, which are always pressed by the pusher 6, are pushed out from the staple box 1 one by one using the push plate 7 provided in the holder 2, and documents are bound by bending them on the holder 2. However, at the same time that the last staple 5 loaded in the needle box 1 is pushed out by the push plate 7 and bent on the pedestal 2, the pusher 6 is inserted into the notch 7-1 of the push plate 7. Since the mating claws 6-1 engage automatically and elastically, the push plate 7 is held in the needle box 1, and as shown in FIG.
and the staple pressing body 3 remain united against the elasticity of the spring plate 8. Thus, with this aspect, it is possible to immediately determine that the staple 5 is absent even without expanding the needle box 1 and the staple presser 3 about the shaft 4 as a fulcrum. Further, when the pusher 6 is moved backward to load the staple 5 into the needle box 1, the engagement between the notch 7-1 of the pusher plate 7 and the engaging claw 6-1 of the pusher 6 is automatically released. Then, the staple pressing body 3 provided with the pressing plate 7 is pushed up by the elastic action of the spring plate 8 and returns to its original position.

In this way, in the present invention, the last staple loaded in the needle box is pushed out and bent by the pusher plate, and at the same time, the needle box and the staple pressing body remain combined, and with this aspect, it is possible to eliminate the presence of staples in the needle box. This makes it possible to easily determine whether staples are missing, which prevents work losses such as bringing staples to the place of use or pressing the staple presser repeatedly without knowing that the staples are missing. By loading the paper, it is possible to improve the efficiency of document filing work.

In addition, in this invention, staples are loaded through the loading port provided on one side plate of the needle box, so compared to conventional products that load the staple by opening the needle box and staple presser, it is easier to load staples. It has the advantage that work can be done with one touch.
